-------------------------------------

             Summary: Client should throw exception to warn users when the 
configurations set by program options conflict with those set by -D
                 Key: FLINK-24223
                 URL: https://issues.apache.org/jira/browse/FLINK-24223
             Project: Flink
          Issue Type: Bug
          Components: Client / Job Submission
    Affects Versions: 1.13.0, 1.12.0, 1.11.0
            Reporter: Zhanghao Chen


h2. Problem

Currently, program options (e.g. -d, -p) has high precedence over configuration 
options set by -D or -yD at client side. This may cause confusion for users, 
especially for those program options without args. For example, if a user sets 
-Dexecution.attached=false without setting -d (they may not be aware of the 
existence of this option), they will find that the configuration value does not 
take effect.
h2. Proposal

Client should throw exception to warn users when the configurations set by 
program options conflict with those set by -D.
